WARP-KNITTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 395,077, dated December 25, 1888. Application filed January 21, 1886. Serial No. 189,238. (No model.) Patented in England December 19, 1884, No. 16 ,677.

T [6 whom it may concern.-

Be it known that I, HENRY BLACKFORD PAYNE, of Radford, in the county of N ottingham, England, have invented certain new and useful Improvements in VVarp-Knitting Ma chines, (for which Letters Patent have been granted to me in England under date of December 19, 1884, numbered 16,677,) of which the following is a specification.

chine for making knitted warp fabrics, which machines are commonly known as warp-machines, the improvements being designed with a View to simplify the construction of 1 5 the actuating mechanism and enable the same to be driven faster than heretofore.

The invention consists of a warp-machine which combines a needle-bar having bearded needles, a presser-bar, a point or sinker bar,

a fixed sley-bar, guide-bars, mechanism by which motion is imparted to the needle-bar, presser-bar, point or sinker bar, and guide bars from a longitudinal cam-shaft, and devices for imparting endwise motion to the guide-bars, as will more fully appear hereinafter, and finally be pointed out in the claims.

In the accompanying drawings, Figure 1 represents a front elevation of the machine partly broken away. Fig. 2 is a vertical cross- 0 section on the line 1 2 of Fig. 5. Fig. 3 is a vertical cross-section on the line 3 4, Fig. 5. Fig. 4. is a vertical cross-section on the line 5 6, Fig. 5.

taken above the cam-shaft; and Fig. 6 is a plan View, partly in section, of the mechan This invention relates to an improved ma Fig. 5 is a horizontal cross-section of a portion of the machine, the section being ports in proper bearings the needle-bar rockshaft d, presser-bar rock-shaft 6, point or sinker bar rock-shaftf, guide-bar rock-shaft g, and v the hand-wheel shaft h. 'The working parts of the machine consist of a needle-bar, (1, having bearded needles d", an independent presser-bar, e, a point or sinker bar, f, and one or more guide-bars, 9 all of which bars are connected by suitably-shaped levers to each of their respective rocking shafts d, e, f, and g. The shaft h, by belt or otherwise, transmits motion to the shaft C for actuating the parts.

The needle-bar d is connected with its rockshaft (1 by means of levers d that are preferably provided with circular openings, so as to vallow the cam-shaft C to pass through them.

There may be any desired number of levers d for supporting the needle-bar d. Each of the levers-d is provided with rollers or contact-pieces (1 that bear on the surface of suit-' ably-shaped cams D, arranged in pairs for each lever (1 both of which cams are keyed to the cam-shaft 0, there being two cams for each lever (1 as shown in Fig. 5. These cams, '7 5 by acting upon the levers d impart a vertically-reciprocating motion to the needle-bar d. The relative positions and shape of these cams D are clearly shown in Fig. 3.

The presser-bar e is arranged to come in contact with and press the beards of the needles, and it is supported bylevers e which' are fastened to the rock-shaft 6. (See Fig. 3.) Said levers e each carry a roller or contactpiece, a that bears upon a-properly-shaped cam, E, carried by the shaft 0, as shown in Fig. 4, there being one cam E for each'leve'r e The rollers e are pressed against their respective cams E by means of springs .6 that are secured at one end to the levers e and at their opposite ends to the framing. As the cam E rotates the presser-bar 6 will be alternately pressed against the beards of the needles cZ by said cams and drawn away from said needles by the springs 6 The pointebar f is secured to the upwardly-extending arms of elbow-levers f that are attached to the rock-shaft f. The ends of the lower arms of the elbow-levers f carry rollers or contact-pieces f that bear upon suitable 10o levers g, one row for eachlever.

cams F, that are carried by the cam-shaft (I,

there being one cam F for each lever f The rollers f are pressed against their respective j cams F by means of springs f, that are secured at one end to the levers f and at their opposite ends to the framing of the machine. (See Fig. l.) The action of the springs f and cams F serves to give the sinker-barf through the medium of the lovers f a shortreciprocating motion that is nearly horizontal The point or sinker bar f supports the points or sinkers f which are cast in leads and fast- The needles (Z pass bel ened to the bar f. tween the sinkers said points or sinker-s acting to secure the loops formed on the bearded needles.

Just below the point or sinker bar f there is a stationary sley, 1', fixed to a bar, i, which is supported on fixed brackets 1 as shown in Fig. 2. The needles (Z pass through and rise and fall in this sley, such sley forming a bed upon which the work rests. Below and at the front of the sley i is provided a roller, 7, which receives the fabric as the same is knitted by the machine.

As many longitudinal guide-bars g as are required are guided in forked arms g that are attached to the ends of forward -bent levers g, which levers are secured to the guide-bar rock-shaft g. The guide-bars g are supported on the levers g and arms g by pins g", that are carried by the guide-bars, which pins pass through holes in the levers g and arms g as shown in Figs. 1, 5, and b. The guide-bars 9 receive endwise motion by the following means: At one end each guidebar is secured to a spring, .9, shown in Fig. 1, the opposite ends of said springs being secured to the framing. The opposite end of each guide-bar connected by a rod, g, to the upper end of a lever, g, as shown in Figs. 1 and 6. The levers g oscillate on the fulcrum 9, while their lower pointed ends bear on stud-wheels 9*, carried by a shaft, g, that is journalcd to the framing.

T0 the circumference of the wheels 9 are secured as many rows of studs 5 as there are These studs 9 pass into the wheels g, and are secured in place by means of set-screws g one for each stud. The studs g may be of various sizes or placed at different distances apart, so as to form the diiferent cam-surfaces required to give proper endwise motion to the guide-bars g The studs of each row act to give motion to one of the levers g and one of the guidebars g To the shaft g is also keyed a wormwheel, that receives motion from a worm, that is keyed to the camshaft 0. As the shaft (1 rotates, the stud-wheel g through the gearing y and g, will be rotated. This imparts by the studs on the circumference of the same motion to the fulcrumed levers g", to move the guidebars in one direction, the springs s moving the guide-bars g" in the opposite direction. Said springs by their tension on the bars g also act to keep the ends of the lovers pressed against the stud-wheel g. By this means longitudinally-reciprocaling motion is given to the guide-bars g".

Any desired number of guide-bars and operating-levers and rows of studs may be used. Besides the endwise motion irrrpartml to the guide-bars g by the stud-wheels g and sprin 5 they receive a baeluvard-and-l'orward or laterally-oscil]ating motion by means of levers 1 that are secured at one end to the rock-shaft g. The free ends of the levers g are forked,the end of each fork carrying a roller or contact-piece, Each roller g rests upon a cam, G, that is carried by the cam-shaft C. This is clearly shown in Fig. 2. As the cams G rotate, the shaft y will be oscillated by thelevers g contacting said cams, thereby moving the guide-bars back and forth by means of the arms g.

The upper part of the machine is provided with a beam-tackle,l(, to receive the beams of yarn K as required to supply the needles.

The several n'lovements of the parts are as follows: The needle-bar (.l' rises vertically about half its motion when the lapping of the threads upon the needles is made by the guide-bars g, which are moved to and fro by means of the levers g, actuated by the cams G and longitudinally by the springs s and stud-wheels 9". The needles then rise to their full extent to pass the laps under the beards of the needles. They then descend, and just as the beards oi the needles enter the points f the presser-bzu' e presses the boards into the eyes of the needles, and the work is then knocked over. The points f then moveback. and forward in order to secure the last loops made.

The special :ulvantages resulting from this improved construction of warp-lmitting machines consist in the various motions being shortened in order to gain speed. This is accomplished by reason of the presser-bar be- 1 ing detached from the point-bar and having an independent motion which permits the shortening of the motion of the point-bar. The needle-bar also receives a shorter motion by reason of the presser-bar being detached and carried farther back, thereby permitting a greater motion of the guide-bars. 13y giving independentmotion to the n'esser-bar and point or sinker bar the double friction of the threads caused by combining the two bars in one is avoided, and thus very fine silk can be used to great advantage. The needles and other parts of the machine may be arranged to work either vertically, as shown, or horizontally, or in any other position, if desired, and the terms vertical and horizontal as applied to these parts are only used to render their relative positions and movements clear.

Having now described my invention, what I claim is 1. The combination of a necdle bar having bearded needles, a separate and independent presser-bar, a point or sinker bar, a fixed sleybar, and guide-bars, a etun-shait having cams,
